Be it known that l, Envvrn n. Earner, a

. citizen of the United States, and a resident of Cripple Creek, in the county of Teller and State of Colorado, have invented a new and Improved Method of Lubricating lneurnatic Machiner of which the following is a full, clear,"a11 exact description.

. One of the problems involved in the praci0 tical operation of'pneumatic machinery is lubrication of the surfaces of the Working parts exposed more or less toatmospheric pressure. Lubricants of a lirpiid nature cannot be advants eously employed owing to the tendencv o. the aiupressure to displace the liquid, the result being that the lubricant is wasted and the surfaces are insuihciently lubricated. I. i in the present invention 1 employ a lubrizo cantoi a solid nature and utilize a current of compressed air as the vehicle by which the lubricant is carried to the surfaces which it p is desired to lubricate. in. the course of ex.- v"tended. experime ts I have discovered that otent factor in dissolving a charge of splid or pressed lubricant is the action of the moisture present in the current of compred sed air on the charge, and in practicing my nvention 1 therefore place the lubricant o cliarge in such proximity to the path of the current that the moisture contained therein .,\will have access to the lubricant'in such a Way as to dissolve the latter gradually and slowly. The lubricating solution thus formed is conveyed in the air-current to the surfaces of the machinery. Further objects and advantages of the in f ventiop will appear in the course of the subjoined description, and the actual scope thereof will be defined by the annexed claims. a

Reference is to behad to the acc unpany- .ing drawing, forming a part of this specification, in which the figure represents a vertical .,t5"'sectional elevation through one form of apparatus suitable for carrying my process into effect. I 1 v 1 .In the apparatus shown I employ a casin, 5, having threaded nipples 6 7 for the attach- =o ment of pi cs adapted to carry a current of compressed air to and from lubrica device. This casing is provided Wits laterally eXtendingmember 8, which is closed at its outer extremity by a suitable cap 9.

The member 8 of the casing is adapted to contain a holder 10, which may be clamped at any desired point of adjustment Within said casing member by a. suitable form of clamp such as the l i sensor-cw 11. lhis holder 10 carries or sustains a charge of solid lubricant, such as A, and the holder is adapted to present the lubricant "in a position Where it is exposed to access by the moisture present in a current of compressed air which traverses the casing 5 of the lubricator.

it will be understood that I do not limit myself to the employment oiany particular form-oi apparatus for car ying the process into eiiect nor to the location of the iubricator device at any particular point in the path or adjacent to the path of said air-current. in some cases it is sufllcient to place the lubricant charge in a trap acent to the path. of the air-current, so that the moisture present in the air Will be trapped into contact with the lubricant charge. I have found that a trapped arrangement of the charge is su'liicient in some cases to supply the necess volume of dissolved lubricant to the aircurrent, particularly where it is not desirable l to economize in the consumption of the lubricant charge.

in many cases it is suiiicient to place the charge A in a position wherein it is exposed to access by the air Without interposing said charge directly in the path of the air-current, and thereby subjecting it to mechanical abrasion due to the impact of the swiftly-moving current of air directly on the solid charge.

Having thus described my invention, claim as new and desire Patent- 1.. The method oi lubricating pneumatic, machinery, Whicl consists in dissolving a lubricant by a current of compressed air, and conveying the dissolved lubricant by such current to the surfaces to be lubricated.

2. The method of lubricating pneumatic machinery, which consists in exposing a 111-. bricating charge to the action of moisture present in a current of compressed air, the dissolved lubricant being carriedby the aircurrent to the surfaces it is desired to lubricate. l 3. The method of lubricatin i machinery which consists in subjecting a lubricating charge to the combined disintegiatl ing and dissolving action of an air-curreht g pneumatic ;harge of solid lubricant by the and the moisture present therein, the air-cur rent being the vehicle by which the dissolved lubricant is conveyed to the surfaces to be lubricated.

4 The method of lubricating pneumatic machinery, which consists in interposing a lubricant charge in the path of an air-current;

issolving the charge by the action of the current; and conveying the dissolved charge to the surfaces it is desired to lubricate.

5. The method of lubricating pneumatic inachiner I, which consists in dissolving a moisture present in a current of compressed air, sus pending the particles of dissolved lubricant mechanically in the current, and utilizing the current as a ehicle for carrying the lubricant to the surfaces it is desired to lubricate, In testimony whereof I have signed my name to this two subscribing Witnesses.
